I have been a Function client for 3 yrs and it has greatly helped me and my husband improve my health. They are constantly improving their website, testing process and streamlining the amount of vials for annual testing. Also adding additional testing for those with specific needs. During the three years I have had numerous questions and the customer service has been awesome. My husband and I both get the testing and it is the best investment in our health. We are in our 70s.
